My notes:

Jenkins killed the job after 15 minutes.

I increased the job's "Timeout minutes" from 15 to 45 minutes.

The emulator prompts to send usage statistics to Google on every run. I
need to find a way to disable that. I don't see that problem after the
first run when I run the steps ad hoc on my own machine. I bet seeing it
is an artifact of how cleanly the Jenkins Android Emulator Plugin starts
the emulator on every run. I hope there's a way to turn it off without
compromising on starting from a clean state.

The prompt comes from DDMS. The presence of a `ddms.cfg` file in
`$ANDROID_SDK_HOME/.android` with the contents below prevents the
prompt.

The Jenkins Android Emulator Plugin has code that's clearly intended to
set up `ddms.cfg` with `pingOptIn=false`. Is that not sufficient? Is it
not executing? Is something else cleaning up `ddms.cfg` after it
executes?

I deleted the `.android` directory in the Jenkins job directory and
re-ran the job. It prompted me to send usage statistics when the
emulator launched. Before dismissing the dialog, I looked at the newly
created `.android` directory. It contains a `ddms.cfg` file containing
only `pingOptIn=false`, just as I would expect from reading the Android
Emulator Plugin's source code. I suspect that that configuration was
once sufficient to prevent the dialog and isn't sufficient anymore. It
seems `pingId` is required now.

Empirically, the following `ddms.cfg` is sufficient on my machine:

    pingId=0

I should change the Android Emulator Plugin to create `ddms.cfg` with:

    pingOptIn=false
    pingId=0

I expect that will prevent the usage statistics dialog in both old and
new versions of the Android SDK, assuming that `pingOptIn=false` worked
in some older version.

I'm using the following version of `emulator` installed via Android
Studio 0.4.0:
